Technical field
The utility model belongs to building and heating refrigeration and energy-saving and emission-reduction facility, particularly relates to a kind of energy tower-soil thermal storage
Couple buried pipe ground-source heat pump system.
Background technique
Underground is stored the container of heat by traditional ground-source heat pump system as one, in temperature higher season
(summer) by the heat storage of building interior to underground, makes the reduction of building interior temperature.It is incited somebody to action in temperature lower season (winter)
It is building heating that the heat extraction for being stored into underground, which comes out,.This is a kind of ideal state, is found in actual application, the summer
The refrigeration duty in season and the thermic load in winter are extremely difficult to balance.Especially in severe cold area, the refrigeration duty of summer is much smaller than winter
Thermic load, if be used alone soil source heat pump carry out heat supply in winter, for many years operation will lead to heat pump taking from underground
Heat is greater than system summer operation to soil heat exhaust, and the thermal balance of soil will be destroyed, and the soil moisture can gradually decrease, heat
The pump coefficient of performance also can gradually be lower.
To overcome the problems, such as soil heat balance by destroying, many researchs all propose the sun for this problem at present

Thermal storage equipment is simple, and investment and maintenance cost are lower.In no central heating network, and do not have enough roofs or other
When solar thermal collector is installed in space, it is also able to achieve across the season utilization of natural energy using air-source heat accumulation method, is severe cold
Area provides new way using soil source heat pump heat supply process.
But outdoor air heat exchanger is only to carry out simple heat exchange, air themperature by outdoor fan coil and air
It is higher can accumulation of heat, but accumulation of heat effect is lower than solar heat-preservation.
